First, you should subscribe to the list, otherwise you will always be moderated. For the iSCSI, just can use 'targetcli' for setting up iscsi-target (yum whatprovides "*/targetcli") and allow it in the firewall (firewall-cmd --add-service=iscsi; firewall-cmd --runtime-to-permanent) . On the client install multipath (device-mapper-multipath) and iscsiadm (yum whatprovides "*/iscsiadm") , then check the man to configure multipath (if you use a separate test VM) and the examples of the man page for iscsiadm for discovering and login to the iSCSI target. Don't use that client for production purposes as iscsid needs some tuning for using with multipath (timeouts) /oVirt should have everything needed/. In the end, 'lsscsi' should show your iscsi block device on the client and you can play with it.

Honestly, it is just from a lack of understanding of what is happening when it does break (as it is for us when doing a hypervisor install on a fresh box). Normally, I can just dig through the stack and figure out what is happening. There are enough areas where I don't have some foundations that I'm not able to do so here (yet). For example, I don't quite understand iSCSI, Multipath, etc enough to know what is breaking, and why. I'm accustomed to being able to dig deeper at each level until I can generally see what is breaking. This confusion will go away as I get a bit more experience and have a "map" of what is going on on this level. FWIW, I started reading the Libvirt book previously mentioned and it's pretty straight forward. It looks like I just need to get through this enough to get a good foothold so that I can figure out how to either fix things when they break or point out properly why something is breaking (so I can get the appropriate help). > > Do you have some specific areas you would like to improve? > Actually, yes :) In: 1. Learn libvirt more (in progress) 2. Review source for vdsm-tool to have a better sense what is going on 3. Setup an iSCSI system so that I can make luns, build a system, play with storage pools this way Thanks for asking this. It's an interesting question.
